Christopher Columbus in a letter speaks of having seen on this coast, which he calls Cariay, a sculptured tomb in the forest as large as a house; and Mr Helps imagines the Spanish conquerors sailing up the coast and beholding amidst the trees white structures "bearing some likeness to truncated pyramids, and, in the setting sun, dark figures would be seen against the horizon on the tops of these pyramids;"[II-27] but as he is describing no particular voyage, some allowance may be made for the play of his imagination. Mr Boyle is enthusiastic over "the vast remains of a civilization long since passed away," but far superior to that of Spain, including rocks cut down to human and animal shapes, artificial hills encased in masonry, streams turned from their courses, and hieroglyphic sculptures on the cliffs,--all in the Mosquito wilds. As a foundation for this, three men who descended the Rio Mico and Blewfields River from Libertad, Nicaragua, to the sea, claim to have beheld extraordinary ancient works. These took the form of a cliff cut away where the river passed through a narrow cañon, leaving a group of stone animals, among which was a colossal bear, standing erect on the brink of the precipice as if to guard the passage. The natives reported also to Mr Pim the existence of grand temples of the antiguos, with an immense image of the aboriginal god Mico (a monkey) on the banks of this river; but when subjected to cross-questioning, their wonderful stories dwindled to certain rude figures painted on the face of a cliff, which Mr Pim was unable to examine, but which seemed from the native description similar to the cliff-paintings at Nijapa Lake in Nicaragua, to be described on a future page.[II-28] [Illustration: Golden Image.] [Sidenote: COLOSSAL BEAR AND GOLDEN IMAGE.]
